Book Description
Differential cross sections for elastic pi -p scattering were measured at eight energies for positive pions and seven energies for negative pions. Energies ranged from 310to 650 Mev. Fifty-one scintillation counters and a matrix-coincidence system were used to measure simultaneously elastic events at 21 angles and charged inelastic events at 78 pi -p angle pairs. Events were detected by a coincidence of pulses indicating the presence of an incident pion, scattered pion, and recoil proton and the results were stored in the memory of a pulse-height analyzer. Various corrections were applied to the dnta and a leastsquares fit was made to the results at each energy. The form of the fitting function was a power series in the cosine of the center-of-mass angle of the scattered pion. Integrntion under the fitted curves gave values for the total elastic cross section. The importance of certain angularmomentum states, particularly the D/sub 13/ state near 600 Mev, is discussed. Several possible explanations are given of the enhancement in the pi /sup -/-p cross sections near 600 Mev. (auth).

Book Description
Differential cross sections for elastic [pi]-p scattering have been measured at eight energies for positive pions and seven energies for negative pions. Energies ranged from 310 to 650 MeV. These measurements were made at the 3-BeV proton synchrotron at Saclay, France. A beam of pions from an internal BeO target was directed into a liquid hydrogen target. Fifty-one scintillation counters and a matrix-coincidence system were used to measure simultaneously elastic events at 21 angles and charged inelastic events at 78 [pi]-p angle pairs. Events were detected by a coincidence of pulses indicating the presence of an incident pion, scattered pion, and recoil proton and the results were stored in the memory of a pulse-height analyzer. Various corrections were applied to the data and a least-squares fit was made to the results at each energy. The form of the fitting function was a power series in the cosine of the center-of-mass angle of the scattered pion. Integration under the fitted curves gave values for the total elastic cross section. The importance of certain angular-momentum states, particularly the D13 state near 600 MeV, is discussed. Several possible explanations are given of the enhancement in the [pi]−-p cross sections near 600 MeV.
